matched pair
Two things alike
A matched pair is two items selected or manufactured to be as similar as possible, used together where consistency matters.
In electronics, matched pairs of transistors or tubes share nearly identical characteristics for balanced circuits.
In statistics, matched pairs are subjects paired by similar traits to control for variables.
The term extends to anything deliberately paired for compatibility: a matched pair of carriage horses, matched pair of speakers.
